Differences of the reconstructed stature in an early Medieval population depending on Pearson's regression equations.

On the basis of 238 male and 230 female skeletons, derived from a Medieval cemetery from Gruczno, Northern Poland, limb bones' proportion was determined. Substantial differences (d > 1 standard deviation) were established in 30% of the individuals, which, according to the relative relations among the separate bones, were divided into 6 groups. For separate individuals of each group a body height was calculated on the basis of Pearson's regression equation (Rösing 1988) as well as separately their arithmetic means for single limb bones and for two bones. The analysis of the absolute differences (the average and maximum values) among all the reconstructed body heights show that the calculated body height depends on the limb proportion. The degree oft the dependence does not seem to depend on the limb proportion group because the most significant differences for both sexes are connected with other proportion groups. The differences in the reconstructed body height are larger for the female skeletons.
